As I write this at 3:30 EDT, Hurricane Arthur’s maximum sustained winds are pegged at 90 miles per hour, and conditions are already deteriorating along the North Carolina coast. The storm has accelerated and is intensifying, according to the National Hurricane Center.
It is expected to reach Category 2 strength when it passes over or near the coast of North Carolina. That means winds of 95 to 100 miles per hour for the Cape Hatteras area at about 8 a.m. tomorrow.
There is also a possibility that Arthur could strengthen to Category 3 status, but the odds are relatively small.
No matter what, this hurricane poses very significant flooding risks for coastal areas, as the experimental map above from the National Hurricane Center shows. It is quite possible that flooding from the storm could cause North Carolina’s Outer Banks to become cut off from the mainland.

Flooding will be the result of storm surges Hurricane Arthur’s winds push up. Often, the greatest risks to life and to property comes from storm surge. Here is a map showing what to expect from the Carolinas up into Virginia and Delaware:
As Hurricane Arthur continues to move up the Eastern Seaboard, significant storm surges can be expected farther north too. For an interactive map of predicted storm surges from Arthur, click here.
Bottom line: This is a serious storm. No one should be taking it lightly.
